What’s In It? HR Conventional 10W-40 Hot Rod Motor Oil

In the factory performance glory days of the late 1960s and early 1970s, most car manufacturers recommended 10W-40 viscosity oil for Big and Small Block muscle car engines. Driven’s HR Conventional 10W-40 Hot Rod Motor Oil is the perfect choice for these classics, as it uses conventional petroleum base oils to provide excellent compatibility with “old school,” cork-and-rope seals. It treats cars with older engines the same way oils did when those immortal horsepower monsters rolled off the showroom floor. This oil is also designed with a secondary-style ZDDP which provides excellent wear protection for cams, lifters, rocker arms, distributor gears, pushrods, wrist pins and cylinder bores.
The oil features a 10W-40 multi-grade formula that provides for easier starting and less start-up wear than straight-grade or heavier-viscosity oils. It also includes the same anti-wear package that the U.S. military employs for storage and transport of combat vehicles and equipment. HR Conventional 10W-40 Oil features unique lubricant technology that prevents rust or corrosion caused by extended periods of storage – or by the use of Ethanol-blended fuels – making it perfect for classic American muscle cars that only see the street in ideal driving weather.
